Maritime transport is responsible for approximately 90% of global trade, playing a fundamental role in the world economy. However, this importance comes with a significant challenge: reducing greenhouse gas (GHG) emissions.

In this context, decarbonizing maritime transport has become a priority, with global targets driving the sector toward adopting more sustainable practices.

Why is decarbonization important?

Currently, maritime transport contributes about 3% of global CO₂ emissions. Without concrete actions, this number could rise, jeopardizing efforts to combat climate change.

The focus on decarbonization aims to align the sector with the goals of the Paris Agreement, which seeks to limit global temperature increases to 1.5°C.

Global initiatives for decarbonization

Several organizations are leading the transition to more sustainable maritime transport:

• International Maritime Organization (IMO): The IMO has set a goal to reduce the sector’s emissions by 40% by 2030 and 70% by 2050 compared to 2008 levels.
• Zero-Emission Corridors: Initiatives such as the Zero-Emission Shipping Mission promote routes with vessels that use alternative fuels and innovative technologies.
• Green Shipping Programs: Regional programs, such as those in the European Union, encourage research and development of green solutions.

Technologies for decarbonizing maritime transport

• Alternative fuels:
  • Green ammonia: Produced with renewable energy, it is one of the promising alternatives to replace fuel oil.
  • Hydrogen: A clean option, ideal for smaller and medium-sized vessels.
  • Biofuels: Derived from biomass, these provide a short-term solution while new technologies are developed.
• Wind and solar energy:
  • Technologies such as rotating sails, solar panels, and hybrid systems are being incorporated to complement traditional propulsion.
• Energy efficiency systems:
  • Laser alignment: Ensures optimal equipment performance, reducing energy losses.
  • Optimized propulsion systems: More efficient propellers and engines lower fuel consumption.
• Sustainable structural repairs:
  • Technologies like the SPS (Sandwich Plate System), applied to ships and offshore assets by Metalock Brasil, enable repairs with less environmental impact, reducing the need for material replacement and waste.

Challenges and opportunities in Brazil

With its extensive coastline and one of the world’s largest maritime export markets, Brazil has immense potential to lead the sustainable transition. However, it faces challenges such as:

• Limited infrastructure for alternative fuel supply;
• Lack of tax incentives for adopting green technologies;
• A shortage of skilled professionals.

Despite these obstacles, companies like Metalock Brasil are actively contributing by offering technological solutions that meet international sustainability standards and promoting technician training to meet future demands.

Decarbonizing maritime transport is essential to ensure a sustainable and competitive future. Innovations in fuels, energy efficiency, and alternative technologies are paving the way for change. Companies that invest in sustainable solutions not only contribute to environmental preservation but also position themselves as leaders in a rapidly evolving market.

At Metalock Brasil, we are committed to supporting the maritime industry with advanced solutions, collaborating for an efficient transition toward sustainability.
